i 7 1 1 11 1 i L1 1 I u u I Au PATENTEUHARZSIQYS SHEET 1 p 3 ADJUSTABLETOOL SUPPORT ON VEHICLE FOR MINING This invention relates to a machinefor working on a rock, earth or other mineral face to form a tunnel orremove material. It can be used in coal orother mines. For the sake ofconvenience only the machine is hereinafter and in the claims referredto as a mining machine.

It is an object of the present invention to provide a mining machinewhich has a greater versatility in earth working capacity than existingmining machines.

According to the present invention there is provided a mining machinecomprising a base, a first carriage slidable along the base, 'a cradlemounted on the first carriage for rotation about a vertical axis, a boomparallel with the longitudinal axis of the base, rotatable about its ownlongitudinal axis, and pivoted on the platform for movement about ahorizontal axis, a platform mounted on the boom and pivotal about ahorizontal axis at or adjacent the leading end of the boom, and a secondcarriage for mounting an earth-working tool and slidable relative to theplatform.

As a result of the present invention the earth-working tool can beoperated as follows:

i. it can be advanced forwardly of the base in a horizontal attitude oran upwardly or downwardly inclined attitude,

ii. it can be oscillated transversely to each side of the longitudinalaxis of the base, the total transverse swing being, for example 45,

iii. it can be disposed normally to the boom and rotated while in thisattitude through 360,

iv. it can be subjected to a combination of the actions defined in (i)to (iii) above.

The mining machine preferably has a material removal facility and forthis purpose there is disposed rearwardly of the machine and preferablyon or connected to the base a winch operatively connected by cable orwire rope and sheave means to a slush bucket in advance of the miningmachine and movable transversely thereof to move cut material laterallyof the machine.

An embodiment of the present invention will now be described, by way ofexample, with reference to the accompanying drawings, in which:

FIG. 1 is a side elevation ofa mining machine accord ing to theinvention;

FIG. 2 is a corresponding plan view showing the machine in a differentattitude;

FIG. 3 is a sectional view of the boom of the machine;

FIG. 4 is a part-sectional detail of the boom;

FIG. 5 is a plan view on the line V-V of FIG. 3;

FIGS. 6 to 9 show different earth working attitudes which can be adoptedby the machine; and,

FIGS. 10 and 11 are views showing the material removal facility of themachine.

Referring to the drawings, the mining machine comprises a sledge-likebase and can be advanced along a roadway in a mine in the conventionalmanner.

A carriage 21 is slidably mounted on the base 20 and is movableto-and-fro therealong by a double-acting hydraulic ram 22. A cradle 23is supported on the carriage 21 for oscillation about a vertical axis 24under the action of a pair of double-acting hydraulic rams 25 connectedbetween the cradle 23 and the carriage 21 and with the vertical axis 24therebetween. The cradle 23 can be oscillated 45 to each side of acentral plane (see FIG. 8).

The cradle 23 supports a boom 26 and under the action of a pair ofdouble-acting hydraulic rams 27 mounted at one end at locations 28 onthe cradle 23 and secured as indicated at 29 to the boom 26, the lattercan be pivoted about a horizontal axis 30 upwardly through an angle of35 and downwardly through an angle of 10 (see FIG. 7).

The boom 26 can also be rotated through 360 (see FIG. 9) about its ownlongitudinal axis. The means for doing this can be seen in FIG. 4 andincludes a pinion 31 fast with the boom 26 and meshing with a rack 32.This rack 32 is acted on by two hydraulic rams 33, 34, the ram 33 beingin its collapsed position and the ram 34 in its extended position. Itwill be manifest that linear movement of the rack 32 under the action ofthe rams 33, 34 will rotate the pinion 31 and consequently the boom 26.

The boom 26 has pivoted thereto at its front as indicated at 35 aplatform 36 which can be pivoted relative to the boom 26 from asubstantially horizontal position to a substantially vertical positionby a double acting hydraulic ram 37.

Slidably mounted on the platform 36 under the control of a double-actingram 38 is a carriage 39 which mounts an earth-working tool, for example,a hydraulically-operated hammer 40. The carriage 39 and hammer 40 cantherefore be advanced relative to the car riage 36 and consequently theboom 26.

The hydraulic control circuit for the abovedescribed machine is ofconventional construction known to those skilled in the art of hydrauliccontrol and includes an oil supply, pump means, piping, various controland safety valve, and pressure indicators. The circuit is manuallycontrolled by a bank 41 of seven control valve disposed with a seat forthe operator on the cradle 23.

From the above it will be seen that the earth working tool, i.e., thehammer 40 can i. be advanced with the boom 26 relative to the machinebase 20;

ii. be advanced relative to the boom 26;

iii. be pivoted to a vertical position relative to the boom 26;

iv. be rotated through 360 (boom rotation);

v. be upwardly and downwardly inclined (boom inclination);

vi. be directed to either side of a central plane (boom oscillation);

vii. be subjected to combinations of movements (i) to The hammer 40itself is also, of course, hydraulically operated.

There is, therefore, provided an extremely versatile earth-workingmachine.

The machine is provided at its front with flood lights 41, an impulsewater spray (not shown) which when the hammer 40 is being operated andwhich serves to restrict dust, and a dozer blade 42 or other fixed oradjustable protective shield.

Outriggers are preferably provided at the sides of the machine, whichoutriggers are adjustable and/or removable.

The rear of the base 20 is provided with two coupling devices 43 toallow attachment to the machine of a debris removal facility.

The debris removal means is a slushing arrangement consisting of ahydraulically-operated winch 44 fastened to the machine via the devices43 and a slush bucket 45 in advance of the machine. The winch 44 andbucket 45 are connected by cables passing round sheaves. The cables 46pass from the winch 44 round sheaves 47 at the side of the base and atthe front of the dozer blade 42 and around further sheaves 47 in advanceof and laterally of the machine, which sheaves 47 are suitably anchoredin the ground.

With this arrangement, as is conventional, the winch 44 causes the slushbucket 45 to be moved transversely of and in advance of the machine toremove cut material directly out of the path of the machine.

The winch controls are indicated at 48.
